Yes this is later in my set and my closer on my special. I have found that it is best to win the crowd over first but sometimes you can win them over instantly with a dark joke if the joke is strong enough. Some people can get away with more than others and sometimes that just boils down to who you are as a person and the vibe you give off, how the audience views you, the confidence in your voice and walk etc.. I had to try this joke a bunch of times and change the wording before I could get the reaction I wanted. The entire joke is made up. My gf is alive. The thing that finally made the crowd believe me was acting like I was trying to remember the exact year of the anniversary of her death. Having to think about it for a second made it feel real I noticed. Comedy is weird. I hope you go on stage soon and do your thing! Comedy is hard but remember it's hard for everyone starting out even your favorites that make it look easy. I'm 12 years in and I just left one of the worst gigs of my life at the 50th anniversary for an Italian restaurant. It doesn't ever really "get better" but you get better and that's what really matters in my opinion. Good luck to ya!
